Tree Indiana Native Quercus phellos [Willow Oak] Somewhat tolerant of city conditions. Oak wilt and scales, and many other oak tree pests, though none considered very serious. Low maintenance, long-lived tree. Use Northern sources in Indiana.
Tree Quercus robur 'Fastigiata' [Columnar English Oak] The tightly columnar 'Fastigiata' provides a strong vertical accent, and is far more popular in the Midwest than the straight species. Powdery mildew on the leaves can be a significant problem. Seed propagated 80-90% true to type, thus variation can also be a problem.
Tree Indiana Native Quercus shumardii [Shumard Oak] The Shumard Oak is a handsome tree that is drought and air pollution tolerant, and but can also be used in rain gardens. Transplanting and establishment can be difficult.
Tree Ulmus × 'Homestead' [Homestead Elm] Dutch elm and phloem necrosis resistant, but susceptible to the elm leaf beetle. 'Homestead' was formed from a cross between Ulmus minor, U. x hollandica, and U. pumila.
Tree Ulmus minor [Smoothleaf Elm] Moderate resistance to the Dutch elm disease pathogen, Ophiostoma ulmi, which has led to the near extinction of the American Elm (Ulmus americana) in the U.S.
